T 0 all whom-it may concern:

Be it known that we, SonEN ROBERTSON SKov and TERANCE SGULLIN, citizensof the United States, residing at Cleveland, in the county of Cuyahogaand State of Ohio, have invented certain new and useful Improvements inDoors for Passenger-Cars; and we do declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention relates to improvements in doors for passenger cars and inmeans for operating the same, particularly of the payas-you-enter ty e,and the invention consists in a door a apted especially for the side andfront of a motor car which is capable of being folded and opened andclosed by mechanism initially under control of the motorman in thevestibule, all substantially as shown and described and particularlypointed out in the claims.

- In the accompanying drawings, Figure 1 is a side elevation of thefront portion of a car showing our new construction of door and theoperating parts connected therewith.

Fig. 2 is a side view, enlarged, of the mechanism connected with theupper portion of the door. Fig. 3 is a plan view of ,the front portionof a car with the vestibule, taken on a section line at or near thefloor of the car and at one point showing-the floor broken away anddisclosing operating parts beneath. Fig. 4 is a sectionalplan of thefront part of the car shown in Fig. 3 and showing especiallv the door.

As thus shown the invention provides for entire cont-r01 of the door bythe motorman from hisposition inthe vestibule of the car and through ahand controlled lever L within the convenient reach of the motorman. Tothese ends B represents the car' body as a whole including thevestibule, and C and D represent the door, or the two sections thereof,front and rear. The front section C is narrower than rear section D tofacilitate folding and getting the door speedily and completely out ofthe way of passengers, and suitable hinges 2 support the front sectionupon the front edge of the rear section and on' which the front sectionis adapted to swing and fold back flat against the rear section, dottedlines Fig. 4. The said door is shown herein as located atone side of thevestibule outside the transverse sliding door E at the immediate frontof the car proper, and is adapted to open inward on hinges 3 and 4 atits rear edge against the fixed partition F and to fold its frontsection on the rear section as it opens. Door by which the motormanenters his own room slides behind said partition F, which standsdiagonally across the vestibule to make room for passengers to depart orenter. Usually this way is closed against entrance and is used only forexit. The said door C and D is operated as a whole through lever L,which is pivoted at or in the floor of the vestibule and has )ositivemechanical connections with the and close the same. These connect-ionscom- )rise the mechanism arti'cularly shown in igs. 1 and '2, and wiichconsist of a bell oor to open I the floor of the vestibule and connectedwith the lower short end of lever L by means of a link rod J and a shortinternally threaded joint 5 at its end through which adjustableconnection between said rod andlever is made, providing thereby for theright working relations of the parts.

A link or rod K extends from the longer arm 6 of lever H to arm 7 rigidwith the lower end of hinge or pivot projection 4 which is rigid withrear door D. Said projection or shaft extends down through one of thebeams of the floor of the vestibule in this instance and has said arm 7rigid with its lower exposed extremity and in such relation to the dooras to become. an operating arm or lever to turn the same on its hingesand which the means for controlling the front section of practicallymakes a right angled piece of the parts 4 and 7. A screw connection 8 isalso provided in this case between rod. K and arm 7 so as toexactlyadjust the parts for operation when they are first ut in place orafterward as may be re uireii, and in this Way a positive mechanicaoperating connection 18 established between the inotormans lever L andthe door to turn the door as a whole on its hinges 3 and 4 and open andclose'the same.

Now, in order that front door section C shall coo erate with section Dand itself be autoinatica ly folded and unfolded, we provide themechanism seen in Figs.. 2 and 4, in which said door ordoor section C isshown as having a stud or post N fixed rigidly to the top thereof, Figs.1 and 2, in line with or above 1 toothed member 10 is made the mediumfor slotted head V and the carries the rod 12, which. threaded in saideke for adpistment. Nut 16 is designed to e adjusted back and forth inrespect to pivots 3 and 4 of section it by rotating the screw on whichit is mounted slioahie in a suitable guideway in hracliet By theadjustment of nut 1 on screw 15 we-are enabled to iii; and maintain thealinement of l 1" sections as well as obtain the folding of ie outersection back against the inner section when the whole door is-open, asshown in dotted lines, Fig. 4.

lihe rack R is c-rried by an oppositely slots oi. which run on post Nabove and below or on opposite sides of pinion 10. This adapts the rackR to its '0 erations with or upon pinion 10 and gives tl fe rack all therun it requires as the door swings on its hinges 3 and l and the frontsection swings on its hinges 2 and whereby said section is folded andunfolded automatically. The entire arm comprising rack R and parts 12and 17 swings with the door on pivot 18 throughout all its movements,and said partsare so adjusted that the two sections will be in straightalinement when the door is closed and folded upon each other when itisopen. The foregoing construction provides positive means ioropening andclosing door C in respect to door D when the latter is operated by themotorman directly through lever L and the several. adjustments describedare intended to provide for the movements of. both doors or sections insuch I measure and to such extent as they may require for harmoniousaction in all their joint operations and relations. Any suitable meansother than a hand lever may be used yto open and close the door throughthe medi- -.um of thebalance of the mechanism herein described. Thus,fluid power may be utili'zed to advantagc 111 some instances.

It is obvious that compressed air or other power agencies may beemployed the door mechanism hereiubefmc and these may take the placesupplement the same.

What we claim is:-

1. A car having a two section side door and a lever and connections tooperate the rear section comprising an arm rigid with the otten] andrear of the rear section, a bell. cranklever fixed on the bottom of thecar and a pivoted lover and link to actuate said bell crank lever, alink connecting said bellcrank lever with said. arm on the door, andseparate connections for the front part of the door engaged. with thetop thereof and adapted to automatically control the same.

2. A car and a door in the side thereof having front and rear sectionshinged together and the rear section having a hinge projection fixed onits bottom and rear and a lever to operate descri bed, oi lever ll orprojection to open and close the entire door, in combination withdevices to automatically open and. close the front section of the door,said devices comprising a pivot post on the top and rear of said sectionand a pinion fixed on said post, a slotted head slidably mounted on saidpost and a rack thereon engaging said pinion, said rack pivoted to swingwith the door, and a pivotal y fixed arni'enouter section of the door isswung when the rear section is opened or closed.

3. In cars, a sectional foldingdoor and means to open andclosc the same,in combination with means to automatically control the position of theouter section in respect to the inner section comprising a post on thetop of said outer section and a pinion fixed on said. post, a rackengaging said pinion and means supporting said rack on said post, a yokewith which said rack is rigidly connected, a screw supported on the Wallof the car and a nut thereon having hinged connection with said yoke.

In testimony whereof we sign this specification in the presence of twowitnesses.
